John Lennon's Art, Colored by Yoko, Tours on the Beatle's 70th BirthdayBy ARTINFOPublished: November 11, 2010

Boulder, CO. John Lennon is being celebrated around the world this year, marking both what would have been his 70th birthday and memorializing the 30th anniversary of his assassination, with most paying tribute to the widely loved music he made first with the Beatles and later in his politically charged solo career. But Yoko Ono, the singer's widow, is taking pains to make sure that his lesser-known vocation as an artist is not forgotten, working to bring his lithographs, serigraphs, and drawings to audiences around the United States — as she did last weekend at a venue in downtown Boulder, Colorado.Called " IMAGINE " — The Art of John Lennon," the show was organized by Yoko Ono along with Legacy Productions and Bag One Arts, who together package tours of the Beatle's artwork. The show was held to benefit the Boulder County AIDS Project. Other the past 18 years, Ono and Legacy have produced as many as 20 exhibitions of Lennon's work per year.During his life, the Beatle rarely had the opportunity to show his work in galleries — a result of "art world snobbery" about his music celebrity, Ono told Boulder Weekly — but he practiced the visual arts from a young age, attending the Liverpool Institute of the Arts in the years before the Beatles' explosion onto the music scene. Encouraged to exhibit his art by Ono, Lennon eventually showed his wiry drawings at such venues as the prestigious London Art Gallery, where eight pieces of his art were deemed obscene and confiscated by authorities in 1970.Ono, a renowned artist whose (loud) work was included in a MoMA exhibition this year, has attracted some criticism for coloring in a number of her husband's drawings after his death. Saying that she was advised by "some very professional people" to add the attractive hues — otherwise exhibitors wouldn't "hang the work in the windows; they'll just put it in a back room or something," she says — Ono told Boulder Weekly that "John probably would not have minded," as they used to do much of their work together anyway.
